[0073] After the tobacco dust collector has been used for a period of time, the filter bags in the tobacco dust collector will gradually accumulate dust, tobacco particles and other pollutants, causing the filter bags to be blocked, reducing the working efficiency of the dust collector. When the filter bags are seriously blocked, it will also affect the normal operation of the dust collector and affect normal production work. Therefore, it is necessary to clean the filter bags in the tobacco dust collector regularly to ensure the dust removal effect and maintain the normal operation of the equipment.

[0074] For small tobacco dust collectors, the number of filter bags that need to be cleaned is small, and manual cleaning is usually used.
